Gustatory differences in hypothyroid and hyperthyroid tasters and non-tasters.
Gustatory differences in Phenylthiocarbamide (PTC) tasters and non-tasters were studied in hypothyroid and hyperthyroid subjects. After presenting for PTC sensitivity, gustatory responses to 7 dilutions of test solutions for glucose (sweet), sodium chloride (salt), citric acid (sour) and quinine sulphate (bitter) were studied in PTC tasters and non-tasters. The intensity and pleasantness responses for 4 basic tastes were measured on a 7-point and 6-point category scale respectively. Sixty percent of subjects of hyperthyroid and 40% of hypothyroid subjects were tasters. Hypothyroid subjects showed more gustatory differences as compared to hyperthyroids. The diminished intensity perception for sweet and bitter taste was much more prominent in non-tasters than tasters hypothyroids. The greater hedonic value for salt was largely observed among hypothyroid tasters.
